To all whom it may concern:

- Be it known that I, OSCAR GRISMORE, re-- sidin at McCook, in thecounty of Redwillow and tate of Nebraska, have invented certain 5 newand useful Improvements in Spouts for jSiftm Machines, ofwhich thefollowing is a spec' cation. p

Myinvention relates to certain new and useful improvements in sifter-souts for use 10 'in connection with sifting-mi ls and machinery to takethe place of the usual cloth stockings now 1n commonuse for connecta ingthe feed-spouts with the vibratingportion of the machine andforconnecting the '15 discharge-spouts of the vibratingportion of themachine with the outlet members of the machine.

' Generically my invention includes a tele- 'scopic s out constructed ofsheet metal to be 2o adjusta le to. the difierent lengths toenable it tobe used on machines of different makes, and'one section ofthe spoutconnects with 'the feed-aperture of the machine, while the other sectionconnects with the discharge-ap- 2 5 ertureof the apparatus throu 'h themedium aving a felt of a telescopic connection,

washer or packing interposed] between the two telescopic portions 0 vthe connection to enable the desired motion to be maintained parts ofthe machinel without endangering t e structure, arrangement, .orconnection of the spout after it has been once placed in position.

. M invention also includes means for main 5 .taimng the spout in itsadjusted position and 5 means for counterbalancing the weight of thespout to. always hold it in its set positions with respect to the partswhich it connects;

Primarily my invention has for its object 40. to provide aspout of thischaracter of a' very simple economical construction, which can be easiland cheaply manufactured and which will readily and effectively serveits intended purposes.

5 With 0th r'obj ects in view than have heretofore been enumerated theinvention also comprises certain novel construction, opera.- tion, andarrangement of parts, all of wh ch will be first described. in detail,and then spe- 5o cifically pointed out in .theap'pended'claims,

reference being had was accompanying v; drawings, inwhichmm Figure 1 1sa pers ective view showlng my invention as applie for use. Fig. 2 is anen- 5 5 larged side elevation of my invention. Fi 3 is a verticallongitudinal section thereo Fig. 4 is a cross-section on the line 4 4 ofFig.

3. Fi .5 is a cross-section taken on the line.

5 5 of ig. 3. Fi 6 is a cross-section taken on the line 6 6 of ig. 3.

Referring now to the accompanying drawings, in which like numerals andletters of re erence indicate like parts in all of the figing its lowerend rolled up to provide a peripheral roll 1*, and the sa d section 1 isprovided with an annular bead l spaced slightly inwardly from the end ofthe roll 1, to receive a washer or packing 2, of felt or other suitablematerial, between the bead 1 and the peripheral roll .or bead 1 asshown. The tubular section 1 has abase-plate 1, which is nailed,screwed, or otherwise secured over the bottom of the sifterdischarge-aperture, as shown.

3 designates a second tubular member having a base-plate 3, which issecured to the floor or a pocket in the floor, into which the materialis to be discharged when my invention is used between the sitter-machineand the discharge therefor; but when my invention is used between thefeed-troughs F and the sifter machine Sv then the member 1 is fastenedto the feed-trough F- and the member 3 to the sifter S'over theinlet-aperture thereof. Y

The tubular section 3 is of greater diameter than the tubular section 1and is ada ted to receive the lower tubular portion 4 0 the siftermember 4, which portion 4 is provided at its lower end with a roll orbead 4 and an annular bead 4, spaced upwardly to receivev a washer or.packing 5, of felt or other suitable materia Telescopically fitted intothe section 4 of the spout 4; is a second spout-section 4, whose u perend is enlarged, as at 4 to telesco ic-- aily fit over the tubularmember an (to snugly receive the washer 2, as shown, thus forming atelescopic connection between the s out-section 4 and the tubular member1 as s own.

The spout-section 4, together with its washer or packing 5, istelescopically fitted into the section 3, as shown.

' 6 desi nates a clamping-band taking around the outer tubular section.4*" of the spout 4 at its other end, whereby the two sections/i4'are-clamped together to serve as a single spout after they have beenadjusted wit ,res ect to the members 1 and 3. v

To ho d the spent 4 in its proper positlon ures, 1 designates a shorttubular section havtion 4* and is'secured at one end 7 to section itsother endsecured td the member 3, wherebythe werght of the s cut 4will'be sustained by the'spring 7 to hol it always in its proper Icqlflfclative position with respect to the mem- 15 here 1 and 3 to serveas a buffer or balancespring for the spout 4, thus allowing'for the,

necessary motion in themoving parts of the sitter withoutinterfering ordisconnecting we the spout 4 from the members 1 and 3.

"The spring 7 also serves as a: compensator to compensate forthemovement of the mov- "ableparts of the sifter mechanism S.

From the foregoing'it is thought, that I haveprovided-a' very simple andeffective, 25,

By maki g Y ,to'all ow it to be used on in chines of 'difierent;

makes and types, and the spring 7 also holds the spout from rotatmgdue-to theacti'on'of the sitter mechanism.

' In practice my i I factured in difierentsizes andstyles to sup plymachines of different capacities. From the -fore oing description, takenin struction, and many advantages of my n vention. will bereadilyiulnderstood by thosg c it appertains, an

skilled in the art tow I desire to say th tmany slight changes in 5 thedetailed construction, operation, and'de- Sign of parts may be madewithout departing from the scope of the invention or the ap-' pendedclaims. 7 Having thus I claim, and r 1. A. e I
